What is the effect of moving a charge along an equipotential line?
No work is done, and the electric potential energy remains constant.
What happens to the electric potential (V) as the distance (*r*) from a point charge approaches infinity?
The electric potential (V) approaches 0.
What is the effect of doing work *by* the electric field on a charge?
The electric potential energy of the charge decreases.
What is the effect of doing work *against* the electric field on a charge?
The electric potential energy of the charge increases.
Define electric potential energy ($U_e$).
The energy a charge possesses due to its position in an electric field.
Define electric potential (V).
Electric potential energy per unit charge. It represents the 'push' available to move a charge.
Define equipotential lines.
Lines or surfaces where the electric potential is constant. No work is done moving a charge along these lines.
What are Volts (V)?
The units for electric potential, equivalent to Joules per Coulomb (J/C).
Define Work in the context of electric forces.
Work is done when moving charges in an electric field, overcoming the electric force.
What happens to the electric potential (V) as the distance (r) from a point charge approaches infinity?
V approaches 0.
What is the effect of doing work *by* an electric field on potential energy?
It decreases the potential energy.
What happens when a charge moves along an equipotential line?
No work is done.
What happens to kinetic energy when it is converted to potential energy?
Kinetic energy decreases and potential energy increases, conserving total energy.
